资源简介：
The 1993 Human Footprint, 2018 Release provides a global map of the cumulative human pressure on the environment in 1993, at a spatial resolution of ~1 km. The human pressure is measured using eight variables including built-up environments, population density, electric power infrastructure, crop lands, pasture lands, roads, railways, and navigable waterways. The 1993 Human Footprint was developed to allow inter-comparability with the 2009 Human Footprint. The data set is produced by Venter et.al., and is available in the Mollweide projection.
《1993年人类足迹，2018版》提供了1993年全球环境累积人类压力的地图，空间分辨率为约1公里。人类压力通过八个变量进行测量，包括建成环境、人口密度、电力基础设施、耕地、牧场、道路、铁路和航道。该《1993年人类足迹》的编制旨在实现与《2009年人类足迹》的相互比较。该数据集由Venter等学者制作，并采用Mollweide投影方式提供。
